## OpenAPI

````yaml api-reference/openapi.yaml GET /.well-known/mcp.json
openapi: 3.1.0
info:
  title: Arlo Health MCP Server
  version: 1.0.0
  description: |
    Healthcare infrastructure for AI agents. Everything an agent needs
    to act in healthcare for its user.

    ## Overview

    This server exposes two interfaces:
    - **MCP** (Model Context Protocol) over streamable HTTP at `/` for AI agents
    - **REST API** at `/api/*` for bots, skills, and direct HTTP clients

    Both interfaces use the same tool handlers and authentication.

    ## Authentication

    OAuth 2.1 with PKCE. All `/api/*` endpoints require a Bearer token.

    Discovery endpoints (no auth required):
    - `/.well-known/oauth-protected-resource`
    - `/.well-known/oauth-authorization-server`
    - `/.well-known/mcp.json` (MCP Server Card)

    ## Service Regions

    Care is licensed by where the patient is physically located when they
    request it, so every conversation carries an ISO 3166-2 `region` code.
    Arlo currently serves California, United States (`US-CA`); an unsupported
    region is refused with `REGION_NOT_SUPPORTED`, whose payload names the
    regions Arlo serves at that moment.
